ANALYTICAL ELASTOHYDRODYNAMIC LUBRICANT FILM THICKNESS FORBALL BEARINGS 6007, 6207, 6307 & 6407 USING HERTZ CONTACT THEORY
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 10
Abstract
Elastohydrodynamic lubrication is the phenomenon that occurs when a lubricant is introduced between surfacesthat are in rolling contact such as rolling bearing. Elastohydrodynamic lubrication (EHL) is an important branchof the lubrication theory, describing lubrication mechanisms in non conformal contacts widely found in manymechanical components such as various gears, rolling bearings, cams and followers, metal-rolling tools, tractiondrives, and continuous variable transmissions. In present work, the elastohydrodynamic (EHD) lubricant filmthicknesses for bearings 6007, 6207, 6307 and 6407 are calculated by the formula based on Hertz’s contacttheory. The developed formula along with inexpensive measuring instruments can be used for online conditionmonitoring of rolling element bearings.
